Chapter 26 Troubleshooting 1 There might be a lot of traffic on the network. Look at the LEDs, and check Section 3.1 on page 28. If the Zyxel Device is sending or receiving a lot of information, try closing some programs that use the Internet, especially peer-to-peer applications. 2 Check the signal strength using the NCC, AC, Zyxel Device Web Configurator, or the client device itself. If the signal is weak, try moving the client closer to the Zyxel Device (if possible), and look around to see if there are any devices that might be interfering with the wireless network (microwaves, other wireless networks, and so on). 3 Reboot the Zyxel Device using the Web Configurator/CLI or the NCC or AC. 4 Check the settings for QoS. If it is disabled, activate it. When enabled, raise or lower the priority for some applications. 5 If the problem continues, contact the network administrator or vendor. 26.5 WiFi Network I cannot access the Zyxel Device or ping any computer from the WLAN. 1 Make sure the wireless LAN (wireless radio) is enabled on the Zyxel Device. 2 Make sure the radio or at least one of the Zyxel Device's radios is operating in AP mode. 3 Make sure the wireless adapter (installed on your computer) is working properly. 4 Make sure the wireless adapter (installed on your computer) is IEEE 802.11 compatible and supports the same wireless standard as the Zyxel Device's active radio. 5 Make sure your computer (with a wireless adapter installed) is within the transmission range of the Zyxel Device. 6 Check that both the Zyxel Device and your computer are using the same wireless and wireless security settings. Hackers have accessed my WEP-encrypted wireless LAN. WEP is extremely insecure. Its encryption can be broken by an attacker, using widely-available software. It is strongly recommended that you use a more effective security mechanism. Use the strongest security mechanism that all the wireless devices in your network support. WPA2 or WPA2-PSK is recommended. The wireless security is not following the re-authentication timer setting I specified. NWA50AX User's Guide 203
